What does 1.8L mean?

[McHaven]

1.8L indicates that the vehicle has a displacement of 1.8 liters, meaning the volume of fluid inhaled or expelled per cycle is 1.8 liters. Below is additional information: 1. A car's displacement refers to the total capacity of all the engine's cylinders. In China, vehicle classification is determined based on displacement size. 2. Displacement refers to the exhaust volume, and the cylinder working volume is the volume swept by the piston from top dead center to bottom dead center, also known as single-cylinder displacement, which depends on the cylinder bore and piston stroke. 3. Engine displacement is one of the most important structural parameters. It represents the size of the engine more accurately than cylinder bore and the number of cylinders, and many engine performance indicators are closely related to displacement.
